Application July 11, 1947, Serial No. 760,224

1 Claim. 1

Our invention refers to a telephone mouthpiece protecting pad. Theprimary object of the invention is to provide a simple and effectivesanitary fiber protector disc adopted to be adhesively fitted to thelips of a transmitter mouthpiece.

The invention essentially comprises a centrally apertured fiber disc,having a coating of adhesive, non-drying substance which will affix thedisc to the mouthpiece, whereby it can readily be removed forreplacement without leaving any residue coating upon the lip.

The aperture or apertures of the disc are sealed by a crepe tissuesheet, whereby sound when closely directed in the mouthpiece will betransmitted clearly over the phone, but all extraneous room sounds ornoises will be deflected or deadened due to the irregular crinkled crepepaper surfaces, which surfaces serve to deflect room sound wavesdirected towards the same at an angle. Hence, conversation may becarried on through the phone without interruptions by room noises. I

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

In the drawings:

Figure 1 is a sectional elevation of a telephone mouthpiece equippedwith a sounding disc embodying the features of my invention.

Figure 2 is an enlarged front face view of the disc with parts brokenaway.

Figure 3 is a rear view of said disc.

Figure 4 is a magnified cross sectional view through a portion of thedisc.

Figure 5 is a magnified form of the disc, showing a plurality ofperforations.

Figure 6 is a magnified cross sectional view through the disc, thesection being indicated by line 66 of Figure 5.

Referring by characters to the drawings, I indicates a fiber disc havinga central enlarged aperture 1' formed therein.

Figure 3 of the drawings illustrates the inner face of the disc, whichface is coated with an adhesive substance 2 of standard make. Theadhesive substance is of such consistency that while it will positivelyadhere to a contacting surface when the disc carrying such surface isremoved from the lips 4 of a telephone mouthpiece 4, the said lips willbe free from adhesion particles, whereby the mouthpiece is maintainedclean and sanitary.

The sound induction aperture l' of the disc has adhesively fitted aboutthe inner surface of the disc, a porous crepe tissue sheet 3, wherebythe aperture opening I is, in effect, closed.

However, owing to the crinkly upstanding surfaces or minute wallsdeveloped in the crepe paper. indirect sound striking the crinkledsurface of the paper at an angle will be deadened, by deflection butsounds directed from the lips of an operator towards the opening I willbe clearly transmitted through the telephone due to the porous nature ofthe sheet.

Hence, a party using the telephone or listening in will not be subjectedto musical sound waves or noises in the room beyond the telephone mouth,which indirect sound waves under ordinary conditions frequently confuseconversation through the phone.

Referring to Figures 5 and 6 of the drawings, a sanitary disc is shownprovided with a series of small apertures l" therein through which thesounds are transmitted, it being understood that otherwise the disc isconstructed similar to that previously mentioned.

From the foregoing description, it is apparent that a sanitary disc isprovided to protect operators from coming in contact with variousmicrobes usually deposited upon the mouth of the phone which is usedindiscriminately, and due to the cheapness and simplicity of this disc,they could be readily replaced from time to time to insure sanitation,it being also understood that the discs may contain Various advertisingmatter.

While I have stated that the disc I can be made of fiber, it is to beunderstood that the same can be made from paper or the like, and theterm fiber is used to comprehend paper. If desired, the disc I can hemade from thin metal, and in this instance the tissue sheets 3 can berenewed from time to time.

Other changes in details can be made without departing from the spiritor the scope of our invention, but what we claim as new is:

A sanitary protector and room sound deflector attachment for themouthpiece of a telephone,

comprising a centrally apertured fiber disc, having its inner facecoated with an adhesive material, the outer edge of the adhesive face ofthe disc being adapted to engage the rim of a telephone mouthpiece, asecond disc of coarse crinkled crepe tissue having its edge adhesivelyengaging the inner face of the first mentioned disc for closing theaperture in said first mentioned disc, the irregular crinkled unbrokensurface of the crepe tissue forming a series of mi,-

nute circular pockets, whereby voices directed into the telephone willpenetrate the crepe tissue, while room sound Waves striking the surfaceof the circular pockets at various angles will be deflected so that theywill not penetrate through the phone with the voice of the direct userthere- SIDNEY J.
